Klout, a startup that measures influence on Twitter, Facebook, LinkedIn, YouTube, and Foursquare, is now integrating Google+.
For background, Klout evaluates users’ behavior with complex ranking algorithms and semantic analysis of content to measure the influence of individuals on social networks. On Twitter, Klout’s influence score is based on a user’s ability to drive action through Tweets, Retweets and more. On Facebook, Klout will examine how conversations and content generate interest and engagement, via likes, comments, and more, from the network’s 750 million-plus users.
Google just released a limited API for Google+ last week, so Klout has been working fast. It’s unclear what exactly Klout will be evaluating in Google+ behavior and use, but Klout’s founder Joe Fernandez tells me that he believes that certain Google+ power users will see their scores go up. But as with Klout’s other integrations, if you link your Klout account with Google+, your score won’t go down.
Of course, there’s data out there suggesting that the public interest in Google+ is waning but the network was opened up to the public today, so that could help increase usage.
A month ago, Klout also added integrations with Blogger, Tumblr, Flickr, Instagram and Last.fm.
